Commercial refrigerated display cabinets are highly professional. They not only have requirements for storage temperature, but also their display properties are very important.

[0003] During normal operation, the moisture in the air inside the refrigerated display cabinet will condense into dew and gradually frost due to the low temperature. These frosts will continue to accumulate to form ice layers and ice cubes, which will not only cause the storage space to become smaller, but also block air circulation and refrigeration cycles, affecting the refrigeration effect of the refrigerated display cabinet. Since the refrigeration equipment needs to run for a long time and at a high load to combat frost, the life of the equipment may be shortened and the cost of maintenance and replacement will increase.

[0018] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation method, structure, characteristics and effects of the utility model are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide a commercial refrigerated display cabinet with an automatic defrosting function, including a cabinet 1, a placing plate 2 is fixedly installed on the inner wall of the cabinet 1, a defrosting device 3 is arranged on the inner wall of the cabinet 1, and a moving device 4 is arranged on the outer surface of the cabinet 1. The defrosting device 3 includes a driving component 32 and a rectangular plate 36, and the output end of the driving component 32 is fixedly connected to a screw rod 31, and one side of the outer surface of the screw rod 31 is rotatably connected to the inner wall of the cabinet 1. The driving component 32 includes a motor and a mounting frame, and the mounting frame is fixedly connected to the outer surface of the cabinet 1. A motor is fixedly installed above the mounting frame, and the output end of the motor is fixedly connected to the screw rod 31. One side of the outer surface of the rectangular plate 36 is fixedly connected to a scraper 37. By arranging the scraper 37, the driving component 32 and the screw rod 31, the scraper 37 can automatically defrost the place where frost is easy to form in the refrigerator;

[0020] The outer surface of the screw rod 31 is threadedly connected with an L-shaped plate 33, one side of the outer surface of the L-shaped plate 33 is fixedly connected with a telescopic rod 34, the outer surface of the telescopic rod 34 is sleeved with a spring 35, one end of the outer surface of the telescopic rod 34 is fixedly connected with a rectangular plate 36, and the two ends of the spring 35 are respectively fixedly connected to the outer surfaces of the L-shaped plate 33 and the rectangular plate 36. Through the cooperation of the telescopic rod 34 and the spring 35, the sponge block 38 and the scraper 37 are squeezed to the back of the inner wall of the refrigerator to improve the defrosting effect;

[0021] Two sponge blocks 38 are fixedly connected to one side of the outer surface of the rectangular plate 36. The two sponge blocks 38 are respectively located on the left and right sides of the scraper 37. The sponge blocks 38 absorb the frost residues left during defrosting to prevent the frost residues from re-condensing into frost in the freezer.

[0022] A slide groove 39 is provided at the bottom of the inner wall of the cabinet 1, and a collection frame 310 is inserted into the inner wall of the slide groove 39. A rectangular cover 311 is fixedly connected to one side of the outer surface of the collection frame 310, and a sealing ring 312 is fixedly connected to one side of the outer surface of the rectangular cover 311. By setting the collection frame 310, the frost scraped off by the scraper 37 falls into the collection frame 310, which is convenient for dumping the cleaned frost.

[0023] The moving device 4 includes a cavity 41, which is opened on the lower surface of the cabinet 1. A bidirectional threaded rod 42 is rotatably connected to the inner wall of the cavity 41, and a handle 43 is fixedly connected to one side of the outer surface of the bidirectional threaded rod 42. By setting the bidirectional threaded rod 42, the two sliders 44 can be moved together or separated.

[0024] The left and right positions of the outer wall of the bidirectional threaded rod 42 are threadedly connected with sliders 44, the bottom of the slider 44 is rotatably connected with a first connecting rod 45, the inner wall of the first connecting rod 45 is rotatably connected with a round rod 46, the top of the inner wall of the cavity 41 is fixedly connected with a positioning plate 47, one side of the outer surface of the positioning plate 47 is rotatably connected with a second connecting rod 48, the inner wall of the second connecting rod 48 is rotatably connected to the outer surface of the round rod 46, and wheels 49 are fixedly connected at both ends of the outer surface of the round rod 46. By setting the first connecting rod 45 and the second connecting rod 48, in cooperation with the bidirectional threaded rod 42, the wheels 49 are moved up and down, thereby achieving the effect of conveniently moving the refrigerator and stabilizing the refrigerator.

[0025] When the utility model is used, the handle 43 is used to rotate the bidirectional threaded rod 42, so that the first connecting rod 45 and the second connecting rod 48 are rotated downward, and the two sliders 44 are moved in opposite directions. When moving, the round rod 46 is pushed downward until the wheel 49 contacts the ground, so that the refrigerator is away from the ground, and then the refrigerator is pushed to the specified position. After reaching the position, the bidirectional threaded rod 42 is rotated in the opposite direction, and the wheel 49 is put into the cavity 41 to place and stabilize the refrigerator. Then, the commercial products that need to be refrigerated are placed on the placement plate 2 in the cabinet body 1. When the interior of the refrigerator needs to be defrosted, the drive assembly 32 is started to drive the screw rod 31 to rotate, thereby driving the L-shaped plate 33 in the cabinet body 1. Sliding back and forth, the L-shaped plate 33 drives the scraper 37 and the sponge block 38 on the rectangular plate 36 to slide back and forth, and through the extrusion under the action of the telescopic rod 34 and the spring 35, the scraper 37 and the sponge block 38 are close to the frosted area on the inner wall of the cabinet 1, and then the scraper 37 scrapes off the frost in the cabinet 1, and the scraped frost will directly fall into the collection frame 310 at the bottom of the cabinet 1, and the sponge block 38 absorbs the frost residue left after the scraper 37 scrapes. After defrosting is completed, the drive assembly 32 is closed, and then the rectangular cover 311 is grasped to take out the collection frame 310 from the slide slot 39, and the scraped frost is poured out. After pouring out, the collection frame 310 is inserted into the slide slot 39 to complete the defrosting.
